Question

我创建了包含复选框的简单页面。在此页面上，用户可以多次检查和取消选中复选框。我想跟踪所有这些事件？我怎么能这样做？

这是我的代码。

app.js

var pmApp = angular.module('pmApp', ['ionic']);

pmApp.controller('CheckboxController', function($scope) {
  $scope.devList = [
    { text: "Device & app history", details : "Allows the app to view one or more of: information about activity on the device, which apps are running, browsing history and bookmarks" ,checked: true },
    { text: "Identity", details: "Uses one or more of: accounts on the device, profile data", checked: false },
    { text: "Calendar", details: "Uses calendar information", checked: false },
    { text: "Contact", details: "Uses contact information", checked: false },
    { text: "Location", details: "Uses the device's location", checked: false },
    { text: "SMS", details: "Uses one or more of: SMS, MMS. Charges may apply.", checked: false }
  ];

  $scope.selection=[];
  // toggle selection for a given employee by name
  $scope.toggleSelection = function toggleSelection(item) {
     var idx = $scope.selection.indexOf(item);

     // is currently selected
     if (idx > -1) {
       $scope.selection.splice(idx, 1);
     }

     // is newly selected
     else {
       $scope.selection.push(item);
     }
   };

});

的index.html

    <div class="list" ng-controller="CheckboxController">
        <ion-checkbox ng-repeat="item in devList"
                      ng-model="item.checked" 
                      ng-checked="selection.indexOf(item) > -1"
                      ng-click="toggleSelection(item)"
                      >
            {{ item.text }}
            <h3 class="item-text-wrap"> {{ item.details }}</h3>
        </ion-checkbox>
<div class="item">
          <pre ng-bind="selection | json"></pre> 
</div>
      </div>

在此先感谢，任何帮助将不胜感激。

您可以使用https://docs.angularjs.org/api/ng/directive/ngMouseover为所有元素制作鼠标悬停计数器：然后使用 https://docs.angularjs.org/api/ng/directive/ngClick记录点击次数，https://docs.angularjs.org/api/ng/directive/ngMousemove记录要移动的鼠标并获取位置：

使用的一切： NG-点击 NG-DBLCLICK NG-鼠标按下 NG-鼠标松开 NG-的mouseenter NG-鼠标离开 NG-鼠标移动 NG-鼠标悬停

以下是一些示例代码：

HTML：

<body ng-app="mainModule">
  <div ng-controller="mainController">
    <h3>1. Click</h3>
    <button id="firstBtn" ng-click="onFirstBtnClick()">Click me</button>
    <strong>RESULT:</strong> {{onFirstBtnClickResult}}<br />
    <br />
    <h3>2. Click with Dependency Injection</h3>
    <label>Type something: <input type="text" ng-model="secondBtnInput"></label>
    <button id="secondBtn" ng-click="onSecondBtnClick(secondBtnInput)">Click me</button><br />
    <strong>RESULT:</strong> {{onSecondBtnClickResult}}<br />
    <br />
    <h3>3. Double click</h3>
    Double-click the square<br />
    <img src="images/square.png" ng-dblclick="onDblClick()" /><br />
    <strong>RESULT:</strong> {{onDblClickResult}}<br />
    <h3>4. Mouse down, up, enter, leave, move, over</h3>
    Move the mouse on the square<br />
    <img src="images/square.png"
         ng-mousedown="onMouseDown($event)"
         ng-mouseup="onMouseUp($event)"
         ng-mouseenter="onMouseEnter($event)"
         ng-mouseleave="onMouseLeave($event)"
         ng-mousemove="onMouseMove($event)"
         ng-mouseover="onMouseOver($event)" /><br />
    <strong>MOUSE DOWN RESULT:</strong> {{onMouseDownResult}}<br />
    <strong>MOUSE UP RESULT:</strong> {{onMouseUpResult}}<br />
    <strong>MOUSE ENTER RESULT:</strong> {{onMouseEnterResult}}<br />
    <strong>MOUSE LEAVE RESULT:</strong> {{onMouseLeaveResult}}<br />
    <strong>MOUSE MOVE RESULT:</strong> {{onMouseMoveResult}}<br />
    <strong>MOUSE OVER RESULT:</strong> {{onMouseOverResult}}
  </div>
</body>
</html>

如果符合您的需求，您可以尝试使用最新的Ionic Analytics。有关其官方博客文章的更多信息：http://docs.ionic.io/v1.0/docs/analytics-from-scratch。

用法很简单（来自additional docs）：

.controller('MyCtrl', function($ionicAnalytics) {

  $ionicAnalytics.track('Purchase Item', {
     item_id: 'lpdsx,
     item_name: 'Leopard Socks'
   }); 
});
